incorporate a hydronic module with a multi-speed pump, as standard.
An optional hydronic module with a variable-speed pump that
automatically adapts to the system requirements is also
available.
Easy integrationThe low noise levels of the 61AF heat pump and
its very compact chassis reduce the noise disturbance from the
unit.
Application flexibilityThe operating range allows outside
temperatures down to -20C and leaving water temperatures up to 65C
for domestic hot water applications.
Availability - Intelligent unit control permits unit operation
in extreme conditions, minimising unit shut-down times.
- Hot water production at 65C is available continuously.
Carrier quality is your guarantee for the safety and durability

The new generation of high-temperature heat pumps incorporates
the latest technological features: - scroll compressors with vapour
injection - low-noise fans made of a composite material -
auto-adaptative microprocessor control - electronic expansion valve
- multi-speed pump.
The high-temperature Aquasnap heat pumps can be equipped with a
hydronic module that is integrated into the heat pump chassis,
limiting the installation to straight-forward operations like the
wiring and the connection of the hot water supply and return
piping.

Hydronic module (option 116)Typical hydronic circuit diagramThe
hydronic module option reduces the installation time.
The heat pump is factory-equipped with the main hydronic
components required for the installation: screen filter, water
pump, safety valve, water pressure transducer, flow switch. The
Pro-Dialog+ control allows integration of system and water pump
protection devices (insufficient water flow rate, water pressure,
water flow rate etc.).
The pump supplied with the hydronic module is a multi-speed
pump.
An automatic pump start-up algorithm protects the heat exchanger
and the hydronic module piping against frost down to -10C outside
air temperature, as standard. If necessary, increased frost
protection down to -20 C is possible by adding heaters to the
hydronic module piping (see option 42).
The hydronic module option is integrated into the heat pump
without increasing its dimensions and saves the space normally used
for the water pump.

Notes: Units without hydronic module (standard units) are
equipped with a flow switch and two
temperature sensors (7 and 9). For units equipped with hydronic
module, the pressure sensor located upstream of the pump
to prevent cavitation is installed on a connection without
Schraeder valves. Depressurise and drain the system before any
intervention.

Units with fans with available pressure for indoor installation
(option 11)This option applies to 61AF units installed inside the
building in a plant room. For this type of installation the cold
air leaving the air-cooled evaporators is discharged by the fans to
the outside of the building, using a duct system.
The installation of a duct system at the air evaporator
discharge line causes a pressure drop due to the resistance caused
by the air flow.
Therefore more powerful fan motors than those used for the
standard units are installed in the units with this option. For
each installation of a unit installed inside a plant room the duct
pressure drops differ, depending on the duct length, duct section
and direction changes. 61AF units equipped with fans with available
pressure are designed to operate with air discharge ducts with
maximum pressure drops of 100 Pa.
Fan discharge connection A square flange is supplied mounted on
the unit. An available standard round flange can easily be
installed at the fan discharge, if the installer prefers the use of
a round connection duct.
The unit is supplied with a grille on the discharge side. This
grille has to be removed before connection to the duct system.
It is advisable to make the connection to the duct system with a
flexible sleeve. If this recommendation is not observed, a lot of
vibration and noise may be transmitted to the building
structure.
Applicable rules for units incorporated into an air duct
system
Ensure that the suction or discharge inlets are not
accident-ally obstructed by the panel positioning (e.g. low return
or open doors etc.).

The 61AF units are equipped with a fixed-speed pump with three
different speeds.
These speeds can be manually adjusted by changing the speed
terminal board inside the terminal box (this operation can only be
carried out by approved personnel). The speed initially selected
corresponds to standard use for heating water loops. If this speed
needs to be changed, the pressure/flow curves for the three speeds
are shown below.
